Sudden Cardiac Death News and Research

RSS

The term sudden cardiac death refers to natural death from cardiac causes, heralded by abrupt loss of consciousness within one hour of the onset of acute symptoms.

Online searches for unproven therapies for COVID-19

A new observational study by a group of scientists explores the rise in the public's fear-driven interest in unproven therapies for COVID-19, particularly chloroquine and hydroxychloroquine, by tracking the internet searches relating to the purchase of drugs in news reports or publicized by public figures. They conclude: "Stay grounded in evidence and fight misinformation." The research letter and accompanying editorial comment are published in the journal JAMA Internal Medicine.

Higher serum EPA levels from prescription fish oil associated with lower cardiovascular events

Higher levels of the omega-3 fatty acid eicosapentaenoic acid (EPA) found in the blood—and not a decrease in triglyceride levels as originally thought—appear to explain the striking reductions in cardiovascular events and deaths seen among people taking 4 grams daily of the prescription fish oil, icosapent ethyl, according to findings from a REDUCE-IT substudy presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology

Critical guidance to identify COVID-19 patients at risk of drug-induced sudden cardiac death

SARS-CoV-2, the virus that causes COVID-19, continues to spread, leading to more than 20,000 deaths worldwide in less than four months. Efforts are progressing to develop a COVID-19 vaccine, but it's still likely 12 to 18 months away.

Having a bath regularly reduces risk of cardiovascular disease

A new study, published online in the journal Heart in March 2020, reports that with hot water, it seems to be a case of washing away health problems – literally. As a result, the more a person uses hot tubs, the better in terms of cardiovascular health. In other words, soaking in hot water daily improves heart health more than having a hot tub once or twice a day.

Study identifies a protein and signaling pathway that may contribute to sudden cardiac death

By studying the sick hearts removed from four patients undergoing heart transplants, researchers have identified a protein and a signaling pathway that may contribute to sudden death in an inherited form of heart disease.

Extreme endurance exercise can increase risk of cardiovascular events

For most people, the benefits of aerobic exercise far outweigh the risks, however, extreme endurance exercise - such as participation in marathons and triathlons for people who aren't accustomed to high-intensity exercise - can raise the risk of sudden cardiac arrest, atrial fibrillation (a heart rhythm disorder) or heart attacks, according to a new Scientific Statement "Exercise-Related Acute Cardiovascular Events and Potential Deleterious Adaptations Following Long-Term Exercise Training: Placing the Risks Into Perspective-An Update from the American Heart Association," published today in the Association's premier journal Circulation.

Sudden death due to heart disease – it could be in the genes

More than 220,000 American adults die suddenly of cardiac causes – a phenomenon called sudden cardiac death. Some sources put it as closer to 400,000. Both inexplicable and distressing, this has been the subject of a new study published in the Journal of the American College of Cardiology and presented at the American Heart Association’s scientific session.

Study sheds light on how HIV infection may increase risk for sudden cardiac death

Researchers reveal initial results from a study of hypertrophic cardiomyopathy

Researchers have revealed the initial results from the world's largest comprehensive study of hypertrophic cardiomyopathy, an abnormal thickening of the heart that often goes undiagnosed and can prove deadly. The condition can present at any age, and it is the most common cause of sudden cardiac death in young athletes.
